Wrap gio.DataInputStream.read_line_async and read_until_async

Wrap the functions and their corresponding *_finish() functions.
Create 'gdatainputstream.override' for these and move two existing
functions there.  Add unit tests.  Re-enable synchronous read_line
unit test and adjust it for new official GIO behavior.  Bug #584285.
